Thanks, I read a lot of that thread. Similar sitch: young kids at home to think about. OM makes WAW feel "special".
I gotta think about the consequences of planned trip. I will inform her that I see it as disrespect. Might just leave it at that and let her stew about it while she's gone guessing what I might do.
InAPickle, the affair and the fact that you are staying put as her "emotional sponge" is what makes her feel like she is ontop of the world.
What you are going to have to do anyhow whether you leave her or stay is to GAL.
Much of what she does around you are a consistent "disrespect". Getting cheated on messed up my erections and feeling of worth. I got it back by living my own life and not worrying about her. Over time the desire to have her back faded and I gained feeling of worth in myself. Also someone who does this to you look less attractive.
You may make and ultimatum, tell her if she continues on this path your going to have to divorce. When she does not stop ( they never do ), have her served at work.
